Product information

Description

The Philips 4000 series HU4210/03 ultrasonic air humidifier in dark grey is designed to maintain optimal indoor humidity levels effectively and quietly in daily home and office environments. Featuring a 3.5-liter water tank and coverage for room areas up to 44 m², this energy-efficient device operates on a 3 W power supply to ensure reliable performance for indoor spaces.

Advantages

This air humidifier utilizes advanced ultrasonic evaporation technology to distribute moisture evenly throughout the room without producing excessive noise. Its energy-efficient 3 W operation ensures minimal electricity consumption during continuous daily use. The generous 3.5-liter water tank allows for extended periods of operation between refills, reducing the need for constant maintenance. The compact dark grey design blends seamlessly into modern home and office interiors while providing consistent indoor climate support.

Suitable for

  • Living rooms and bedrooms up to 44 m²
  • Home offices and studies
  • Daily indoor climate maintenance
  • Quiet environments requiring low-noise humidification

When it may not be suitable

This device is not designed for spaces exceeding 44 square meters, as larger areas will reduce its humidification efficiency. Additionally, it does not feature built-in air purification capabilities, meaning it focuses solely on moisture output rather than filtering dust or allergens.

Key specifications

  • Ultrasonic evaporation technology
  • 3.5 L water tank capacity
  • Suitable for room area up to 44 m²
  • 3 W power consumption
  • AC power supply type
  • Dark grey product colour

How to use

Place the air humidifier on a flat, stable surface within the target room. Remove the 3.5-liter water tank, fill it with clean tap water, and securely reattach it to the main unit. Connect the power cable to a standard AC electrical outlet and switch on the device. Adjust the placement as needed to ensure unobstructed vapor distribution across the room.

What to consider before purchase

  • Verify that your room size does not exceed 44 m² to ensure adequate performance
  • Confirm access to a standard AC power outlet near the placement location
  • Note that this model does not include air purification functions

Regularly clean the water tank and internal components according to the manufacturer guidelines to prevent mineral buildup and maintain hygienic operation.
